This game was bought by someone who loves XCom, the computergame(s). So, naturally, this version was a nice addition to our boardgames. Unfortunately... we were disappointed greatly. At first, you need the app to even read the rules. The rules are big walls of text, sometimes even unclear what needs to happen. Second, either we are super unlucky, or the die are loaded/ unbalanced. We 'missed' prettymuch all attacks. Eventually, we had to add more ufo's, but we'd run out of ufo's. Third, we couldn't even finish the (losing) game, as the app had drained the battery. We barely managed to finish round 3 of 5. We still believe this game has potential... but we're going to make up our own rules and try out our own die. Actually, all the app does is generating random numbers (like: add 2 ufo's to africa), which you can compensate by using D4, D6, D20... So, in all honesty, we seriously cannot recommend this game.
